JOSEPH E. BARRANGER, OF 'IPHILADELPHIA, PENNSYLVANIA.

JAn-cLosU'RE.

Specification of ILetters Patent. Patented Dec. 10, 1912. Applicationl'ed June 13, 1912. Serial No. 703,452.'

To all whom it may concern: A

Be it known that I, JOSEPH E. BARRANGER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Jar-Closure, of which the following is aspecification.

My invention consists ofl a ]arclosure composed of a cap, a gasketwithin the same,.

and an inturned member onsaid cap, the same serving to compress saidgasket in such manner that it embraces the jar as to hermetically closethe jar and prevent' disen` gagement of the cap with the packing un-vless properly operated by superior force.

The invention is satisfactorily illustrated in the accompanying drawing,but the im portant instrument-akties thereof may be varie-d, and so itis to be understood thatrthe invention is not limited to the specificarran ement and organization shown and descri ed.

.Figure 1 represents a central vertical `secf tion of a jar closureembodying my invention in normal condition. Fig. 2 represents a sideelevation of the closure in complete condition. Fig. 3-represents acentral vertical section of the closure shown in Fig. 2; Similarnumerals of reference indicate corrspondingparts-in the figures.vReferring to the drawings 1 designates the neck of a jar formedsuitable material. l

2 desi ates a metallic cap which is composed o. the top 3, the shoulder4 circumferentially around the same and the rim 5 which depends fromsaid shoulder, said rim being deiiectedl laterally forming a rhom boidalchamberin which is fitted the gasket 6 which is of the form of a ringrhomboidal in vertical section, so as to accord with the chamber of therim 5, it being noticed that 'the upper portion 7 of said rim isoutturned in slo ing direction,- the lower portion 8 thereof) isint-urned in sloping direction so as to embrace the upper and lowersloping port-ions of the gasket thus retainingl ythe latter within thechamber of the rim and preventing dropping of the same. y

The central portion 9 of the rim or p0r-` tion intermediate oftheportions y8, 7 is of glass or other' bent inwardly forming the inturnedbead 10.- This forces in the contiguous wall of the gasket forming acircumferential groove therein, thus compressing the body'of the gasketinwardly, its height and thickness being` reduced so that while thegasket primarily loosely encircles the neck of the jar,

it is now so contracted and compressed in both horizontal and verticaldirect-ions resisted by the sloping top and bottom portions ofthe rimproducing wedging actions on the gasket so that the 'latter is morefirmly pressed against the neck of the jar so that it tightly hugs thesame, forming a hermetical joint for the jar which reliably Aand safelyAseals the same, while the'cap under ordinary circumstances retains itspositlon on the neck of the jar without liability of slipping ofil ofthe same. A

The shoulder 4 rests on the edge of the neck of the jar limiting thedescent of the cap in its application to the jar and assisting inseating the cap true in position.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is:"-- 1. In a jar closure, a cap having adepending siderim and a gasket within the same, said rimhavingf-portions at the top and bottom thereof ladapted to embracewedgingly the contiguous upper and lower corresponding portions of saidgasket, and an inturned portion intermediate of said top and bottommembers .adapted to compress inwardly said gasket between said upper andlower portions thereof.

2; A jar closure .consisting of a cap having a side rim with anoutturned slope on the top thereof, and an inturned slope on the bottomthereof, a' gasket within said rim,

lsaid rim having an inwardly projecting bead adapted to compress saidgasket,- inwardly against the contiguous portion of the jar, -saidslopes of the rim being adapted 'to embrace the respective u per andlower f sloping portions of said gas et.

3. A Jar closure consisting of a cap havinga side rim with outturned andinturned portions respectively thereon, a gasket within said 4rlmadapted to be encircled by the same and wedgmgly' engaged by said...fm-n

sloping portions, and an intuined member on said rim adapted to enterthe outer periphery of said gasket thus compressing the lattei' in bothhorizontal and vertical directions While being grasped at the top,bottom and sides byvsmd riln and correspondingly forcing the inner Wallof the body of the gasket against the contiguous portion of the
